You want people to put up their account as collateral? Did I read that right?
This smells like a scam to steal accounts.
Yes and you can be an escrow for their accounts

Does it smells better now?
P.S. if you can't where can I find actual trusted escrow list on that board for my service?
Nobody trusted is going to be interested in doing that. People here are quite against account sellers/buyers and I am sure they will be against account escrowers.
I would not trust anyone with my account and I recommend the same constant vigilance for everyone. What happens if the escrower steals an account? Are you going to compensate the victim?
Either way, this account escrow thing is a bad idea.
